Routine vaccines may cut dementia risk—experts have startling hypothesis on how

Recent studies suggest that routine vaccinations may be associated with a reduced risk of dementia, with vaccines for flu, RSV, and shingles showing particularly strong links. Experts are exploring how these vaccines, designed to combat specific infections, might also bolster cognitive health by training previously untrainable aspects of the immune system. This emerging hypothesis could reshape our understanding of the relationship between immunization and brain health.
